The well is programmed to be drilled to a depth of 1500 metres. The Echidna structure is a look-a-like to the nearby Wombat structure already drilled by lakes. The Strzelecki Formation expected at 920 metres is the main target but the Latrobe Formation above this remains a potential secondary target.
The Echidna High well is located in PEP 157. An overriding royalty of 5% of the wellhead value of any hydrocarbon production is payable to Roma Petroleum NL, a former permit holder.
